NEIV YORK.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 463,934, dated November24, 1891.

Application filed April 10, 1889. Serial N0.306,698. (N0 model.)

0 all whom it may concern:

Be it known that I, WALTER J. BARRON, a :itizen of the United States,and a resident of Brooklyn, in the county of Kings and State )f NewYork, have invented certain new and useful Improvements in Type-WritingMa- I chines, of which the following is a specification.

My invention relates particularly to what is designated as the paper orplaten carriage. In some descriptions of machines as, for instance,theRemington the papercarriage is provided with a hinged rack-bar, which isengaged'alternately by a rigid and by a flexible dog or pawl or tooth,which teeth aontrol the movement of the paper-carriage and I operate toeffect a step-by-step' feed thereof during the operation of the machine.When the carriage has traveled thus to the extreme left of the machine,it is returned to the right by a pull upon the line-space lever, and thepaper is fed forward a suitable distance for the commencement of a newline of writing. During the return of the carriage the rack-bar iselevated to clear the teeth which engage it. In the Remington machinethe rack-bar is provided with a forwardly and laterally extending arm,and the linespace lever is provided with a rearwardlyextending finger,which is adapted to engage with said arm, and the arrangement is suchthat when the line-space lever is pulled to return the carriage and isvibrated or actuated to rotate the platen and advance the paper aline-space distance, its rearwardly-extending finger simultaneouslydepresses the arm above referred to and lifts or frees the rackbar fromengagement with the feed dogs or teeth. When it is desired to releasethe escapement or step-by-step feed for the purpose of permitting thecarriage to travel in either direction without actuating the fingerkeysand without rotating the platen, the said arm of the Remington machineis adapted to be directly depressed by the finger of the operator. Assaid arm is located at the rear of the machine it is inconvenient toreach, and hence it is unsatisfactory to operators.

My invention has for its main object to provide a means whereby therack-bar may be conveniently disengaged from the feed dogs or teeth, andby which with one hand the carriage may be run in either direction andarrested at any desired locality without employing the line-spaceleveror rotating the platen.

To this end my invention consists in combining with the hinged rack-barand carriage frame an independent release-key extending to or near tothe front of the machine; and my invention also consists in othercombinations of devices and features of construct-i011, all of whichwill be hereinafter more fully described, and particularly pointed outin the appended claims.

The expression extending to or near the front of the machine is meant toconvey the idea that the release-key is extended forward of the platenand to a point within convenient reach of the hand of the operator,which is normally upon or over the keyboard. In other words, therelease-key is extended to such point as renders it unnecessary for theoperator to reach back to the rear of the machine, as heretofore, torelease the paper-carriage.

In the accompanying drawings, Figure 1 is a top plan view of a portionof a Remington type-writing machine embodying my invention. Fig.2 is anelevation of the same, looking from the right-hand side. Fig. 3 is aperspective view of one form of construction of my release-key detachedfrom the machine. Fig. 4 is another top plan view of said machinecontaining a modification of my invention. Fig. 5 is a side view of aportion of the same. Fig. 6 is a vertical section taken at the line m ofFig. 4. Fig. 7 is atop view embodying a further modification of myinvention, and Fig. 8 is a side view thereof.

In the various views the same part will be found designated by the sameletter or numeral of reference.

A represents the top plate of the main frame of the machine; B, thepaper-carriage; O, a rail to which the paper-carriage is hinged andserving also as a guide for the rear end of the carriage; D, a way ortrack which supports the front of the carriage; E, a cylindrical platenjournaled in the carriage-frame and provided at one end with aratchet-wheel F; G, a line-space lever pivoted or fulcrumed on a rod II,attached to the carriage-frame; I, a driving-pawl on said line-spacelever engaging with the ratchet-wheel F .I, acurved finger extendingrearwardly from said line-space lever; K,a bar having teeth on its underside and hinged to the carriage-frame; L, an arm extending forward fromthe rack-bar frame at one end and laterally beneath the finger .I andbeyond the side bar 2 of the carriageframe; M, the yielding dog ortooth, and N the rigid dog or tooth of the Remington escapement; O, therocker-bar; P, the rockerarm; Q, the connecting-rod, and R the universalbar or spacing-frame.

Referring now particularly to Sheet 1 of the drawings, 3 designates ametallic or other bent frame or rod provided with a clamp or securingmeans at each end by which it may be readily attached to and detachedfrom the carriage-frame. The clamp at the rear end of the bent rod orstrip is marked with the numeral 4:, and consists, preferably, of aplain plate-like portion formed or shaped to clasp or embrace the upperportion of the rear bar of the carriage-frame, while the clamp at thefront end consists, preferably, of two cars or lugs 5 and 6, adapted toembrace the front bar of the' carriage-frame, the ear or lug (3 beingprovided with a threaded hole to receive the point or shank of a bindingor clamping screw 7, which passes down through a plain hole in the upperlug or cars 6, by which means the frame 3 may be securely and rigidlyattached to the carriage-frame alongside of and exteriorly of the sidebar 2 thereof.

At the point 8 a ever 9 is pivoted to the frame or bar 3. This leverperforms the f unction of a release-key, as will be presently explained. The inner end of this lever is bent to form an eye 10, which isthreaded to receive a screw 11, whose point overhangs thelaterally-protruding arm L of the rack-bar frame, while its onterendextends forward to the front of the machine, preferably beyond the planeof the line-space lever, (but this, of course, is immaterial,) and isbent to loop or ring form for convenience of manipulation. The frame 3is provided with an abuntment 12 for limiting the vibration of the lever9.

The operation of the devices illustrated on Sheet 1 will be understoodto be as follows: \Vhen the carriage has traveled to the left of themachine, the line-space lever may be employed to simultaneously rotatethe platen, raise the rackbar, and pull the carriage back to theright-hand side of the machine, all as heretofore. If it be desired,however, to merely raise the rack-bar and run the carriage to somepredetermined point, the operatorsimply lifts the forward end of therelease-key U, by which movement the rear end of the key is depressed,the arm L forced down, and the rack-bar swung up on its pivotal supportout of engagement with the feed dogs. ()n releasing the front end of thelever 9 the parts all return to their first positions by gravity.

It will be observed here that the releasekey operates upon the rack-barindependently of the line-space lever, and that during the use thereofthe line-space lever remains at rest and that no rotation or turning ofthe platen occurs. This, it will be understood, is often desirable intabulated work and in making corrections.

At Fi 2 the operation of the independent release-key is shown in dottedlines.

Referring now particularly to Figs. 4:, 5, and 6 on Sheet 2, it will beobserved that the release-key is 'made in a somewhat different manner.In this form it is designed for new machines, while in the other formfor machines already on the market or in use. The side bar 2 of thecarriage-frame is provided with eyes or bearings 13 for the shank of the1'elease-key, which at its rear end is provided with a cam, stud, or leg14, that normally rests above the arm L, as shown at Fig. 6, and that isadapted to depress said arm and raise the rack-bar. The front end of therelease-key is preferably provided or formed with a crank-handle 15,although a button or head on the end of the shank might do as well. Inthis modification of my invention, in order to raise the rack barindependently of the line-space lever and without turning the platen itis simply necessary to turn the release-key in its hearings to bring thetrip or lug 14c down upon the arm L, so as to depress the same, as shownclearlyat Fig. 5. A spring may be provided to return the releasekey,orit may be turned back by hand. The rack-bar returns to engagement withthe dogs by gravity as soon as the force is removed from its arm L. Theshank or rock-shaft, with its lug or arm 14 and crank-handle or button15, constitutes a lover of the first order, which acts in the samemanner, essentially, as the straight lever shown in Figs. 1, 2, 3, 7,and 8.

Referring now particularly to Figs. 7 and 8, itwill be seen that therelease key embodies the construction shown at Figs. 1, 2, and 3; but isemployed in connection with a linespace lever differing in constructionfrom the one shown at Figs. 1, 2, and at. In this linespace lever therearwardly-extending finger J for actuating the arm L is omitted and theindependent release-key is adapted to take its place, the forward end ofthe line-space lever being provided with an offset or pin 16, whichextends laterally beneath the releasekey, so that when the line-spacelever is vibrated the release-key will also be vibrated IIO and the armL acted upon thereby and the rack-bar elevated to permit the carriage tobe returned at the same time the platen is rotated; but it will be seenthe arrangement is such that the release-key maybe operatedindependently of the line-space lever for the puyposes hereiubeforealluded to.

In the forms in which my invention is shown carried out in all of theviews, excepting Figs. 7 and 8, it will be readily understood that therelease-key may, if desired, be

' arranged at the left-hand side of the machine,

in which event a duplicate of the arm L or its equivalent is providedthereat for the release-key to work in connection with to raise therack-bar.

Of course, instead of having the arm L attached to the rack-bar frame onthe side of its pivot or hinge opposite that on which the rack-bar isarranged, it may be attached or arranged on the same side and theindependent release-key arranged to lift it (and the of the bar 2 thescrew may be omitted, as the rear shorter arm of the lever is adapted toactuate it directly.
